“I can again thy former light restore,Should I repent me: but once put out thy light,Thou cunning'st pattern of excelling nature,I know not where is that Promethean heatThat can thy light relume.”

“Should we put out the light? And then put out the light. But once put out thy light, I cannot give it vital breath again. It needs must wither.”

“...and in thy voice I catch the language of my former heart, and read my former pleasures in the shooting lights of thy wild eyes.”

“But thou, contracted to thine own bright eyes,Feed'st thy light's flame with self-substantial fuel,Making a famine where abundance lies,Thyself thy foe, to thy sweet self too cruel.”

“I hope thou shalt never retreat beneath the ground. The sun is thy inheritance. The sky is thy birthright. Stay here, my boy, and with the conversation of mankind. rejoice in the light.”

“Give of thy love, nor wait to know the worth Of what thou lovest; and ask no returning. And wheresoe'er thy pathway leads on earth, There thou shalt find the lamp of love-light burning.”
